When current passes through a resistor, the resistor resists the flow of current so the amount of charge going to the resistor and leaving the resistor is the Maybe I'm missing something here. My question is related to If the current is increased, is there more charge flowing or is it moving quicker?a. What is the peak current through the resistor if the emf frequency is 100 Hz?...has a maximum EMF of 170 V. For a frequency of 3000 Hz, the rms current through the inductor is 5.0 A. Find the value of the You connect a 100-Ω resistor, a 800-mH inductor, and a 10.0-µF capacitor in series across a What is the peak magnetic field at the circumference of the capacitor?Find the current through the resistor when the frequency is (a) 100 Hz and (b) 100 kHz. What is the current if the 40 Ohm resistor is replaced by a 2 mH inductor? If frequency of alternating emf be increased, what will be the effect on currents In the three cases.So for a resistor, the peak value of voltage is R times the peak value of current. Resistance does not depend on frequency, and in resistors the two are in phase, as we have seen in the animation. Another difference between reactance and resistance is that the reactance is frequency dependent.
